The dialog will have 71cdf0e10cSrcweir "OK" (replace) preselected if x < y, and "Cancel" otherwise. 72cdf0e10cSrcweir 73cdf0e10cSrcweir- If replacing an installed version x of an extension e with a version y fails 74cdf0e10cSrcweir because y has unsatisfied dependencies, or because y has a license to wich the 75cdf0e10cSrcweir user does not agree, version x is left installed afterwards. 76cdf0e10cSrcweir 77cdf0e10cSrcweir- Checking for already installed versions of an extension is only done within a 78cdf0e10cSrcweir single layer (unopkg versus unopkg --shared; "My Packages" versus 79cdf0e10cSrcweir "OpenOffice Packages" in unopkg gui/soffice), not across layers. 80
